Examine life’s biggest questions, from ethics to existence, with curiosity and critical thinking.
‘Reductio ad absurdum’ won’t help you in an absurd Universe. Throughout history, there have been two main ways humanity has attempted to gain knowledge about the world: top-down, where we […]
If everything eventually dies and decays, is there a way to prolong the inevitable? Our Universe, as it exists today, puts us in an incredibly privileged position. Had we come […]
Are space and time real like atoms are, or is spacetime just a calculational tool? When most of us think about the Universe, we think about the material objects that […]
The inevitable long, slow decline is accelerating, and there’s nothing we can do. The Universe, as it is today, is less active, is forming fewer stars, and is creating fewer chances […]
Thou shalt not conclude “aliens” from insufficient data. When it comes to what’s out there in this Universe, perhaps the only thing that’s greater than our cosmic ignorance is the […]
Avi Loeb says it’s aliens. Every other astronomer disagrees. Here’s why. In 2017, an astronomical event occurred that was unlike any other: for the first time, we observed an object that […]
Think there are habitable super-Earths out there? Think again. Here in our Solar System, we have two very distinct types of planets: small, terrestrial, rocky worlds, with thin (or no) atmospheres […]
There’s a lot to get rid of if we want to get only our Universe out of String Theory. A lot of people, when they learn about String Theory for the […]
Time always moves in the same direction, but what if the Universe were contracting? As we step forward in time, a number of things always seem to happen together. Objects […]
And can we devise an experiment to tell, even when we aren’t looking? One of the most bizarre aspects of quantum physics is that the fundamental entities that make up the […]
There are many things on large scales that also appear on small scales. But is the Universe truly a fractal? If you take a look at the structures that form in […]
It’s 92 billion light-years wide after just 13.8 billion years. And that’s just fine. If there’s one rule that people know about how fast things can move, it’s that there’s a […]
It’s that the Universe can be understood at all. Don’t deafen yourself to its lessons. In a nutshell, 2020 has been a unique year in human history. For the first time […]
It might have been Einstein’s greatest blunder, but it’s our leading theory today. One of the most mysterious components in the entire Universe is dark energy, which — if we’re being honest with […]
We have been rejecting science for far too long. We all need to embrace it. For as long as human civilization has existed, those societies that have embraced science have had […]
If the multiverse is real, where does all the energy for it come from? One of the biggest scientific puzzles, even given our knowledge of the Big Bang, is to understand […]
Everyone is entitled to their own opinions, but no one is entitled to their own facts. Everyone is entitled to their own opinions, but no one is entitled to their own […]
Learn how to get the best views no matter where you are. Every year, no matter what else is occurring on Earth or in the heavens, you can rely on two […]
There’s a flowchart if you aren’t sure. It’s a situation that comes up all too frequently: an expert in their field publicly states a conclusion that is thoroughly accepted by the […]
Our ultimate fate depends on something we’ve barely begun to measure. One of the biggest mysteries in all of physics is dark energy. According to our best observations, the Universe cannot […]
